Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a plasma discharge panel,
and more particularly, to a capillary discharge plasma display
panel having a field shaping layer and method of fabricating the
same. Although the present invention is suitable for a wide scope
of applications, it is particularly suitable for optimizing a
capillary discharge condition, thereby improving brightness as well
as discharge efficiency of the capillary discharge plasma display
panel.
[0003] 2. Discussion of the Related Art
[0004] A plasma discharge panel (PDP) has been considered the most
suitable flat panel display device for a large size, exceeding over
20 inches because it can be realized as a thin and large size flat
panel device. It is also considered to be applicable to a high
definition TV (HDTV). Accordingly, in order to improve a stable
full color display PDP, extensive research and development has been
performed in the display industry.
[0005] Both AC and DC-operated plasma display panel structures have
been employed in operating the PDP. A DC-operated PDP employs DC
electrodes that are in direct contact with the gas, but has to
employ a current limiting device such as a resistor in the drive
circuit to prevent excessive current flow when the gas discharges.
In order to confine the discharge area within a PDP, dielectric
barriers are located between the pixel cells and prevent the spread
of the ionized gas.
[0006] As well known, a dielectric layer is the most commonly used
insulating layer that prevents destructive arc discharge in the
panel. A partial cross-sectional view of a conventional barrier
type AC PDP is illustrated in FIG. 1.
[0007] Referring to FIG. 1, the conventional barrier type AC PDP as
disclosed in U.S. Pat. No. 5,990,854 includes front and rear glass
substrates 10 and 12 that enclose a discharge gas 14 filled in a
discharge chamber. More specifically, row electrodes 16 are formed
on the front glass substrate 10. The row electrodes 16 are
completely covered with a first dielectric layer 20. Similarly, a
column electrode 18 is formed on the rear glass substrate 12 and is
completely buried by a second dielectric layer 22 in order to
prevent arc discharge on the surface of the column electrode
18.
[0008] Generally, the conventional barrier type AC PDP generates
low density plasma, resulting in low brightness and a slow response
time due to a long discharging time on the dielectric wall.
SUMMARY OF THE INVENTION
[0009] Accordingly, the present invention is directed to a
capillary discharge plasma discharge panel having a field shaping
layer and method of fabricating the same that substantially
obviates one or more of problems due to limitations and

[0010] Another object of the invention is to provide a capillary
discharge plasma panel and method of fabricating the same in that
it optimizes a capillary discharge condition, thereby improving
brightness of the capillary discharge plasma display panel.
[0011] Additional features and advantages of the invention will be

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0025] Reference will now be made in detail to the preferred
embodiments of the present invention, examples of which are
illustrated in the accompanying drawings. Wherever possible, the
same reference numbers will be used throughout the drawings to
refer to the same or like parts.
[0026] FIG. 2 is a cross-sectional view of a capillary discharge
plasma display panel (PDP) according to a first embodiment of the
present invention. As shown in FIG. 2, a capillary discharge plasma
display panel of the first embodiment includes first and second
substrates 201 and 202 forming discharge spaces 203-1, 203-2, and
203-3 therebetween and facing into each other. A pair of barrier
ribs 204 define each discharge space. For realizing a full color
representation, the three discharge spaces 203-1, 203-2, and 203-3
representing R, G, and B are required in the unit pixel. Phosphor
conversion layers 205R, 205G, and 205B are deposited on the inner
walls of each discharge space.
[0027] A first electrode 206 serving as an address electrode and a
sustain electrode as well is formed on the first substrate 201.
Similarly, a second electrode 207 serving as a bus electrode is
formed on the second substrate 202. First and second dielectric
layers 208 and 209 are formed on the first electrode 206 and the
second electrode 209, respectively. Lead oxide (PbO), for example,
may be the choice of material for the first and second dielectric
layers 208 and 209.
[0028] At least one capillary 210 per each sub-pixel is formed in
the second dielectric layer 209 for providing a site for capillary
discharge. The number and the dimension of the capillaries may be
varied with sizes of the unit cell and the second electrode 207.
For example, the capillaries have a diameter in the range of 5 and
500 .mu.m. The second electrode 207 may be exposed to the capillary
210. Alternatively, a gap between the second electrode 207 and the
capillary 210 exists, so that the second electrode 207 is buried by
the second dielectric layer 209. The gap may be varied up to about
a half thickness of the second dielectric layer 209. The discharge
spaces 203-1, 203-2, and 203-3 directly face into the capillaries
and each capillary corresponds to each discharge space. A thickness
of the dielectric layer in the second electrode 207 may be varied
to obtain a glow discharge.
[0029] A field shaping layer 211 is deposited on the second
dielectric layer 209 in order to confine a generated field into the
capillary as well as to eliminate a glow discharge. For example,
indium tin oxide (ITO) or transparent conducting oxide (TCO) may be
used as the field shaping layer 211. A thickness of the field
shaping layer 211 is in the range of 5 and 500 .mu.m. A diameter of
the field shaping layer is larger than that of the capillary
diameter by 5 to 50 .mu.m. In operation, the field shaping layer
211 can be floated or may be applied with about 30 to 50% of a
driving voltage.
[0030] Further, a protective layer 212, such as magnesium oxide
(MgO), may be formed on the field shaping layer 211 as well as on
the PbO layer in the gap between the field shaping layer and inner
walls of the capillary for protecting the electrode from erosion by
an ion bombardment. A third dielectric layer (not shown in FIG. 2)
may be deposited between the protective layer 212 and the field
shaping layer 211 for further protection of the electrode. The
protective layer 212 also decreases a breakdown voltage due to a
relatively large value in secondary electron emission. A thickness
of 1 to 20 .mu.m may be appropriate for this purpose.
[0031] A second embodiment of the present invention is illustrated
in FIGS. 3A and 3B. In the second embodiment, a pair of second and
third electrodes 307-1 and 307-2 are formed on a second substrate
302 facing into a first substrate 301, as shown in FIG. 3A. A first
electrode 306 for addressing is formed on the first substrate 301.
First and second dielectric layers 308 and 309 are formed to bury
the first electrode 306 and the second and third electrodes 307-1
and 307-2, respectively.
[0032] In the second dielectric layer 309, at least one a pair of
first and second capillaries 307-1 and 307-2 per each discharge
space is formed therein. As shown in FIGS. 3A and 3B, the first and
second capillaries 307-1 and 307-2 are coupled to each other, so
that each discharge path is formed between the adjacent first and
second capillaries in the direction of about 90 degrees from the
electrodes.
[0033] Similar to the first embodiment, the number and dimension of
the capillaries may be varied with the sizes of the unit cell and
the second and third electrodes 307-1 and 307-2. For example, the
capillaries have a diameter in the range of 5 and 500. Since the
other elements are similar to the first embodiment, detailed
descriptions for those will not be repeated herein for
simplicity.
[0034] A third embodiment of the present invention is illustrated
in FIGS. 4A and 4B. The third embodiment is similar to the second
embodiment except for formation of the capillary. Thus, detailed
descriptions other than the capillary formation are omitted for
simplicity.
[0035] As shown in FIGS. 4A and 4B, only one capillary 410 per each
discharge space is alternatively formed in the direction of about
90 degrees from the second and third electrodes 407-1 and 407-2.
Thus, each discharge path is not formed between the adjacent
capillaries over each second and third electrodes 407-1 and 407-2
in capillary discharge. The adjacent capillaries are formed to have
an angle of about 45 degrees with respect to the direction along
the second and third electrodes 407-1 and 407-2. Therefore, the
adjacent capillaries formed over each second and third electrodes
407-1 and 407-2 are not coupled to each other to form a discharge
path as shown in FIG. 4B. The number and dimension of the capillary
may be varied with the sizes of the unit cell and the second and
third electrodes 407-1 and 407-2.
[0036] In FIG. 5, a schematic diagram of laser optics for forming a
capillary is illustrated. Laser optics comprises a Krypton Fluoride
(KrF) laser 51, first and second mirrors 52 and 53, an attenuator
54, a homogenizer 55, a field lens 56, a mask 57, a third mirror
58, and an objective 59. A substrate 60 is positioned below the
objective 59. Process conditions are as follows: laser wavelength
of 248 nm, 5.times. demagnification, energy density on substrate of
1.8 to 2.2 J/cm.sup.2, and repetition rate of 20 Hz
(pulse/sec).
[0037] A method of fabricating a capillary plasma display panel
according to the present invention will now be explained with
reference to the accompanying drawings.
[0038] Initially referring to FIG. 6A, a first electrode 602 is
formed on a first substrate 601. The first electrode may be formed
602 of ITO in order to pass light through the first substrate
601.
[0039] In FIG. 6B, a first dielectric layer 603 is deposited to
cover the first electrode 602 and separates the first electrode 602
from discharge spaces (shown in FIG. 2 as reference numbers 203-1,
203-2, and 203-3).
[0040] On a second substrate 604, at least one second electrode 605
per discharge space is formed thereon and acts as a bus electrode
in FIG. 6C. For example, the second electrode may be formed of
silver (Ag).
[0041] Further, a second dielectric layer 606 and a field shaping
layer are successively formed on the second substrate 604 including
the second electrode 605, as shown in FIG. 6D. Thereafter, in order
to form a capillary in the second dielectric layer in the
embodiments of the present invention, the laser optics shown in
FIG. 5 is used.
[0042] In FIG. 6E, a first portion 608 of a capillary is formed in
the field shaping layer 607. In FIG. 6F, a third dielectric layer
609 such as PbO may be deposited on the surface of the second
dielectric layer 606 including the first portion 608 of the
capillary and the remaining portion 607-1 of the field shaping
layer. In this process the third dielectric layer is formed to have
a thickness in the range of about 1 and 20 .mu.m. Thus, a break
down of the electrode may be prevented. In addition, it prevents
discharge from occurring at the surface of the capillary rather
than in the capillary.
[0043] In FIG. 6G, a laser beam is applied to within the first
portion 608 of the capillary of the overall surface to form a
capillary in the second dielectric layer 606. In the above
processes, the Krypton Fluoride (KrF) laser having a wavelength of
248 nm is employed using a laser fluence of about 1.8 to 2.2
J/cm.sup.2 or higher and an ablation rate of about 0.111
.mu.m/shot. A laser beam having a spot size of about 1.2
mm.times.1.2 mm is reduced by using a mask.
[0044] A capillary 611 is then formed in the second dielectric
layer 606, as shown in FIG. 6H. Further, a protective layer such as
magnesium oxide (MgO) is deposited on the overall surface of the
third dielectric layer 612 including the field shaping layer
607.
[0045] After each discharge space defined by forming a pair of
barrier ribs, phosphor conversion layers are formed inside walls of
the discharge spaces. Thereafter, in FIG. 6I, a capillary discharge
plasma display panel according to the present invention is
completed by bonding the first and second substrates 601 and 604 by
a seal frame layer (not shown).
[0046] As described above, the present invention provides the
capillary discharge plasma display panel and method of fabricating
the same in which improves brightness as well as discharge
efficiency due to its structure for optimizing capillary discharge
condition.
[0047] It will be apparent to those skilled in the art that various
modifications and variations can be made in the capillary discharge
plasma display panel having a field shaping layer and method of
fabricating the same of the present invention without departing
from the spirit or scope of the inventions. Thus, it is intended
that the present invention covers the modifications and variations
of this invention provided they come within the scope of the
appended claims and their equivalents.
